Referring to Figs. l to 6 the indicator is of the type which is manually operable. ment has all of its parts mounted on a base plate 30 having a spring-pressed fastening pin 3| atY each end thereof to fasten the instrument on al board or other support where desired. A'Ihebase plate 30 is provided at one side, Fig. 1, with a pair of spaced integral guide tracks 32 lextending longitudinally along the plate and parallel to each other with a toothed rack 33 intermediate and parallel to the tracks. These tracks 32 have on one side a groove 34, Figs. and 6, which acts as a guide for the indicating or marking sliders 35 and 36, of which there are two in number, and each slider extends over both tracks 32 bridging the intervening space including the rack 33 and is provided with an actuating knob 49. Also each slider has opposed laterally extending tongues 3l, Fig. 6, which extend into the grooves 34 so that while the sliders can move easily they will not change their position or drop if the instrument is held or mounted in a vertical position. Each slider has a pair of oppositely extending pointed or marking edges 38 and 39, the purpose of which will be explained. y

An intermediate slider or indicator 40, also slides and moves on the guide tracks 32 and has inwardly directed tongues 3'! contacting in and sliding in the grooves y34. The indicator 40' also has side plates tl, Fig. 6, which tend to contact the intern-al sides of the tracks 32 opposite the sides in which the grooves 34 are provided. The plates Y4I as well as the main parts or frame of the slider 40 are provided with vertically elongated slots 42, Figs. 2 and 5, in which a shaft 43 of an actuating roller 44 is rotatably mounted. The 'actuating roller 44 has a pair of spaced peripherially knurled or Ymilled disks 45 between which a gearvll is provided and interconnects said disks 45, the shaft 43, disks 45 and gear 46 being preferably made integral. As shown n Fig. 6 the gear 46 meshes with the rack 33 so that by actuating the knurled edges of the disks 45 by a finger of the operator the slider will travel along the tracks l'ihe slider 40 is also provided with a pair of oppositely directed pointers 4l and 48 in the form of sharp vpins which are suitably secured to the frame of the sli'derfor the purpose which will be explained.

The indicating instrument is provided with a pair of scales 55 and 5i,lFigs. l `and 6, provided in suitable grooves for `this purpose in the base plate. The scale 55 is intended to be fixed, for

the purpose which will be explained, but the scale i 5| is movable and adjustable, which for the latter purpose the scale, in the Aform .of a band, travels in the groove 52, Fig. 6, in the base plate -having overlapping sides 53 along. the longitudinal edges thereof and 'is 'provided with reels or spools 54, Fig. 2, on which the ends of the band are fastened and wound. Each reel 54 on each end of the plate 30, is rotatably mounted in brackets 55 with frictional contact on the adjacent sides and these brackets are suitably 'se- The instrucured on the plate 30 by means of screws 56, Fig. 1. Also each reel 54 is provided with a manual actuating knob or Wheel 51 and an idler roller 58 each of which is rotatably mounted in a 5 bracket 55 to maintain the band down in the bottom of the groove 52. Upon turning either knob 5'| the band 5| may be adjusted, that is by turning the left hand knob 5l, Fig. l, clockwise or the right hand knob counterclockwise each time winding the band or tape 5| on its driving reel in the desired direction and pulling it from the other reel for the purpose which will be explained.

A pair of abutments 59, Figs. 1 and 5, are provided in the base plate 3), one on each side end thereof for the purpose of protecting the pointed ends of the pointers 4l and 38 so that if the instrument is placed or accidently falls on its longitudinal edge on the side adjacent the fastening pins 3| the rather sharp points will not be damaged. Also as seen inA Figs. 2 and 5 the marking edge 65 of the pointers Stand 39 are concave along their longitudinal edge so that the sliders-'f5 and 36 when'brought together against the indicator 40, the .end points of the pointers 38 and 41, and3$ and 48, respectively, will all point and indicate` as near as possible to a single point or mark. r

Each fastening pin 3| is in the form of a push pin 6| mounted in a cylinder 62 secured on each end on the base plate 30. Each pin 6| has an enlarged portion 63 which abuts against the'top end of the cylinder 62 and the pin is provided with a spring 64 and a head portion 65. When the instrument is-placed on a board or other support it is securely held in Vplace by pushing down the pins 6|, but by pulling up on the head por-` tions 55 the instrument vis released. As a safety measure, it is desirable to provide an auxiliary pin 66, Fig. l, fastened to one of the pins 3| by means of a chain lil whereby upon inadvertent release of the pins 3| the instrument will not fall to the floor assuming that the instrument is used on a board arranged at a slight angle from the vertical.

The instrument according to Figs. 1 to 6 oper.- ates as follows, assuming that it is used in connection with a single daysstock market transactions for a particular stock and is used in cooperation with a graph paper; the latter being mounted on a board.

The instrument is first adjusted by setting the pointers 47 and 48, of the slide 43, in the central position so that the pointer 48 will register With the 0 mark 58, Fig. l, on the permanent scale 53. The slides 35 and 36 are then brought against the center slide so that pointers 38 and 47 as well as 39 and 43 will be adjacent to each other. The instrument is then so placed on the graph paper 69, Fig. 31';l on which every verticalline l0 represents the extreme range, highvand low prices of a particular days transactions, and the horizontal lines represent the closin-g vprice for the particular day represented by the left hand vertical line; by placing pointers 38 and 41 on the closing price line l2, the longitudinal axis of the instrument being parallel 'with the lines 16. The instrument is then fastened down by pushing the pins 6| into a board above the instrument as a safeguard. The next step isto adjust the movable band 5| lso that pointers v|58 and 39 will indicate the exact closing price, on the band 5|, of the previous day as represented lby the line l?.l The instrument is now and placing the auxiliary pin es in the board ready for use and as an example, it might be assumed that 'the pointer 48 is set at 35 which represents the previous days closing price. The first sale price may be "36 which is recorded by moving the center slide 40 to the right, Fig. 1, by rotating the disks 45 and therewith the gear y46 which, due to the toothed rack 33, will move the slide 40 which is manually stopped when the pointer 48 registers with the "36 line of the scale This `movement of the slide 40 will move before it the slide to the right so that its pointer 39 will also point to the "36 line on scale 5|. The next transaction is similarly recorded by moving the slide 40 either to the right or left, Fig. 1, depending upon Whether the succeeding transactions are higher or lower than the preceding transactions. It `is obvious that the pointers 39 and 48 as well as 38 and 41 will indicate the range, high and low, as well as the last transaction at any time, and it can be momentarily observed as to the high and low range and last transaction of that day Whereas the pointers 38 and 41 will indicate the same information, but it can be observed in relation to the previous day or days transactions and said pointers are thus preparing the necessary information to `be placed on the permanent record, sheet 69, after the lasttransaction of the day has been completed. It can, for example, be assumed that the slides 35, 36 and 40 are in the position indicated in Fig. 1 at the close of the days transactions in which pointers 38 and 39 indicate the high and low prices as a range with the pointers 41 and 48 indicating the closing price. graph paper 69 to indicate the ran-ge for the day and a short horizontal line 1| to indicate the last or closing price transaction. It is, of course, obvious that the pointers 38 and 41, or merely 41, can be provided with or may constitute an inking or marking pen so that the permanent lines 1.0 may be applied or drawn on the sheet 69 as the transactions on the stock exchange are carried out. It is, of course, obvious that this invention may be used with a well known ticker transmitter or if desired the transactions may be received by any other suitable means.

The purpose of the slot 42 for the shaft 43 is to permit the disks 45 and gear 46 to be raised so that the latter will not mesh with the rack 33 to move the slider 40 quickly without any rotary action,

The indicator of Figs. 7 to 27 is electrically A vertical line 10 is now drawn on the operated and is mounted on a base plate 13 havi.

ing uprights 14 and 15 near each end thereof constituting the frame of the instrument. This instrument also has spring 'pressed push pins 16 at the ends with a safety pin 11 having a suitable length of chain 18 to fasten the instrument on asheet of paper and board in a manner similar to the instrument of Figs. 1 to 6. A number of bars 19, 80, 8|, 82, and 83 are suitably vsecured to and between the uprights 14 and '|75 for the purpose which will be explained. A spirally threaded actuating rod 84 is removably mounted for rotation in the uprights 1-4 and 15.

The 4guide bar 82, Figs. 9, 10, and 10a, is mounted and Xed on the base plate 13 and extends approximately along the center axis of the instrument between the uprights 14 and 1.5. This guide bar 82 is provided with a grove 85, Fig. 9, extending longitudinally in the upper surface of the bar acting as a guide for atongue 86, Figs. 9 and 23, of a guide and actuating nut 81 threaded on and movable axially by the rotation of the actuating rod 84.

The actuating rod 84 is suitably formed as shown in Fig. 23 in which the maior portion of the rod is provided with a spiral thread 88, the pitch of which is determined in relation to the required axial distance it is desired to move the guide nut 81 upon each quarter turn of the rod 84. The left hand end of the rod 84 is provided with a bearing 89 which rotates in a suitable perforation, not shown, in the uprightv 14, Fig. 10a, and the right hand end has a bayonet lock member 90 rotatably mounted but axially rigid on the rod adjacent the end of the spiral thread 88. The lock member 90 has a lever 9| secured thereon and a pair of diametrically opposite lugs 92 on the periphery thereof which latter cooperate with slots 93, Fig. l0, in the upright 15 to removably lock the rod 84 in the uprights. The lock member 90 thus acts as a bearing for the other endVY of the rod 84 and by suitably turning the lock member 90, the rod 84 may be Withdrawn from the instrument to be replaced by another rod having a different pitch of thread 88. Also at the right hand end of rod 84, Fig. 23, a pair of spaced ratchet teeth ofn wheels 94 and 95 and a knurled wheel 96 are secured, or made integral therewith, on the extreme end so that the rod 84 may be manually turned, by the wheel 96, and to facilitate removal of the rod from the instrument.

The indicating device is also provided with an adjustable scale ribbon or tape 91, Figs. 10 and 11, which slides in a track in the upper surface of the scale rod 19. Near each end of the rod 19, th'e tape 91 passes through an opening 98 to a spool or reel 99 each of which is rotatably mounted in side brackets |00 suitably secured on the base plate 13. Each reel 99 is provided with a hand wheel or knob |0| to adjust the tape on the rod 19. As shown in Figs. 10 and 10a, the rod 19 is secured to the uprights 14 and 15 by angle brackets |02.

The rod 80 is merely a reinforcing rod between the uprights 14 and 15, but the rod 8| is an electrical contact rod; and rod 83 is a guide rod for a pair of pointer slides |03 and |04. The electrical contact rod 8| is composed of an insulating base |05, Fig. 15, which is preferably square in cross section and has side strips |06, preferably of brass, secured thereon by screws, and projecting slightly above the upper surface of the insulating base |05 thereby forming guide means for electrical contact strips or ribbons |01 and |08. The ribbons |01 and |08 are preferably made of copper or silver of which the outer end is secured to a U-shaped frame |32 and the other end passes through an opening in the base |05 so that it may spirally curl into a roll |09, Figs. 7 and 7a, so as'to be out of the way, said spiral curl being formed by an inherent tendency of the strip to roll up upon itself against the bottom surface of the base |85. The frame |32 has a knurled turning knob ||0 rotatably mounted therein with a small gear wheel which latter meshes with a gear rack l2 secured along the underside of the base |405. By turning the knob ||0 the extreme end 3 of the ribbon may be adjusted on the rod 8| for the purpose which will be explained, it being seen` from Fig. 7 that there are two strips |01 and |08 each with a frame |32 and anactuating knob ||0 to thus provide contacts 0n the rod 8| with two limit edges |I3 adjustable together, that is relatively toward and away from each other. It will be noted from Fig. 7 that the side strips |06 are spaced from each other'at |'4so as notto short circuit the two contact strips |91 and |88with each other. Each frame |32 is `also provided with lips H5 to frictionalrlycontact the side stripsl so that any jarring of the instrument will not change the adjusted ends H3 of the contact strips |81 and |63. The 'guide' rod 83, Figs. 7 and 11, is secured just above .the base plate 13 to the two uprights 14 and 15, and is provided with a counter-sunk guide track H3. This guide track H6 is made of steel and is adapted to receive the pointer slides |93 and |34, Figs. 7 and 8,' which are made of a magnetic material so that they will adhere to a certain extent to the biottom of the track H6 so that even when the instrument is used on a board which is at a considerable angle relative to the horizontal, the slides |03 and |84 will be maintained in their adjusted or set position, irrespective of the jar of the machine but will nevertheless move with sufficient freedom to any set position.V Each 'slide |83 and |84 is provided with a -dovmwardly extending actuating pin H1 and i I8 respectively anda pointer H9 and |29 respectively.

, In addition to the pointers H9 and |29, there is lan additional lower pointer 2 Figs. 9 and 16, mounted on an arm |22 secured to a curved arm |23, also provided with an upper pointer |24. This arm |23 is removably secured on the cylindrical guidenut 81, Figs. 16 and 23, having a pair of spaced upstanding bosses |25 preferably integrai with the nut.- The nut 81 is provided with internal' spiral threads |29 corresponding to the pitch ci the'threads 88 on the actuating rod 84. The arm |23 also has a forked lower end |21 cooperating with the integral lip 86, Fig. 10, depending from the nut 81 and the arm |23 with its pointers |2| and |24 is removably secured on the nut by a screw |28, Fig. 1.6, which latter main` tains the arm V| 23 on the nut by forcing the lower end |21 against the lip '86 and the upper part into the space between the bosses |25 by means of the laterally projecting bar |29. This bar |29 is preferably soldered or `welded through a perforation in the arm |23, and the outer end of the bar |29 is provided with two spring lcontacts |39 and |3| suitably secured thereon and which are adapted to slide on the bar 8| and ultimately on the contact strips |91 vand |98 respectively, Fig. 11.

The instrument according to Figs. 7 to 26 is operated electrically by means of a pair of solenoi-ds |33 and |34, Figs. 11a, 14 and 24 to 26, both mounted von a plate |35 secured by screws |36 to theupright 15. Each solenoid is provided with aniron core l|36 and |31 connected by means of an :arm |38 land |39 respectively to a bell crank lever |48 and 4| respectively. Eachbell crank lever is provided with an actuating pawl |42 and of` which pawl |42 is adapted to cooperate with the ratchet member 95, `and pawl |43 is adapted to cooperate with the ratchet member 94 when the respective solenoid |34 or |33 is actuated to rotate the rod 84 clockwise or counterclockwise as desired. Also each bell crank lever is provided with a lower bent lug |44 and a screw pin |45 forming a pivot for thepawl |42 and |43 with a spring |46 cooperating with the pin |45, the bell crank lever and the pawl to force the latter against the lug |44, Fig. 24. Each pavvl |42 and |43 is made in the form of a bell crank lever having an upper arm |41, Fig. 19, with an enlarged head |48and a lower arm |49 which latter strikes against the lug |44 provided on each of the levers |46 and |4|.

, Figs. 24 to 26 illustrate the operation of the escapement mechanism when the solenoid |34 is energized to rotate the ratchet wheel and in turnthe rod 84 a one-fourth turn clockwise. Figure 24 shows the position of rest but when the solenoid |34 .is energized the core |36 is drawn upwardly and rotates the bell crank lever |40 counter-clockwise. During this movement, the head |48 of the pawl |42 strikes under the nearest tooth of the ratchet 85, Fig. 25, thereby impartinga one-fourth turn to the rod 84, the outer straight surface |59, Fig, 26 or the surface |56` of the following tooth striking against the side of the pawl to positively lock the rod 84 against further rotation until the solenoid |34 has been die-energized and the parts of the pawl mechanism returned to the position of Fig. 24. Also the next following tooth of the ratchet 95 may alone or simultaneously contact against the lowerv arm of the pawl |42 `to act as a further check against rotation, so that one or both arms of the pawl |42 may act to lock the ratchet 95 and thereby the rod 84 against further rotation until the respective solenoid has been cle-energized.`

The detent |5|, Figs. 17 and 14, is secured to the side of the upright 15 and cooperates .with the locking arm 9| secured on the lock member 99. This detent element |5| has a cam portion |52 and a depressed portion |53 With stop |55 into the depressed portion of which the arm 9| maintains the rod 84 in secure position in the uprights 14 and 15. Each upright 14 and 15 has a small electric light bulb |56 and |51 mounted in a suitable socket of which the bulb |56 is in circuit with the contact strip |91 and the bulb |51 is in circuit with the Contact strip |88.

Fig. 27 shows for purpose of illustration a wiring diagram in which two push button switches |58 and |59 each control one or" the solenoids |33 and |34 through a suitable wiring and battery |60 or any other source of current such as a regular volt current with a transformer, not shown. The wires are connected to binding posts ISI, |32 and |63 mounted on an insulating plate .|64 suitably secured on the vupright 14. Each switch |58 and |59 is connected to the battery |69, switch |53 to binding post |52 and solenoid |33 and switch |59 to binding post |53 and solcnoid |34. Either light bulbs |56 and |51 in two different colors, if desired, will light when contact |30 slides on strip |61 or when contact I3! slides on strip |93.

vFig. 32 shows the device of Figs. 7 to 26 in combination with a continuous recording means for the center pointer, that is to obtain a precise graphic record of all the uctuations' or prices of the entire day or session of the stock market. The continuous graphic recording device |12 includes a means preferably in the form of a cylinder |13 rotatably mounted in a bearing meme ber |14 at one end, on which a graph paperor sheet may be attached andwhich upon the slow rotation of the. cylinder |13 by the motor |15 a stylus or pen |16 on an arm |11 will record a line |18 representing the sales fluctuations. The stylus |18 is rigidly connected by an arm |19 to the guide and actuating nui; 31. It is obvious that the device |12 with its motor may comprise a separate unit or it may be secured to the base 13.

Fig. 33 shows a device for continuously recording the fluctuations on a sheet of paper or graph .paper |38.- For this purpose a telescoping arm |88 with an inking device |83 is hinged at |82 to the nut-81' and this arm may be of square cross section or mayhave any other suitable section. A central bar |8| slides in the hollow arm |80 and is provided with a series of notches |85 which cooperate with a spring lug |84 mounted on the arm |80 and projecting through an opening in the arm. A roller |86, preferably of rubber is rotatably mounted on a lever or axle which is pivotally mounted at |81 to the bar |8| Aand this roller is angularly adjustable relative to the bar |8I. j Thus the axis of rotation of thehinge is horizontal whereas the axis of rotation at V|81 is vertical. By adjusting the roller up or down around |81 determines the character of the angular line which is drawn on the paper sheet |88 by the inking device |83. If for instance the roller |86 is adjusted to the, dotted line position upon the travel of the nut 81 downwardly, the roller |86 will pull the bar |8| slowly out of the arm |80 to draw a lateral line to thus indicate a change in price either up or down but upon the nut 81 moving upwardly the spring |84 and a notch |85 will prevent the bail |8| telescoping into the arm |80, the roller merely sliding on the paper and a vertical line will be drawn bythe device |83. If however the roller |86is adjusted in the opposite angular position the angular lines will be drawn when the nut moves upwardly.

The apparatus according to Figs. 7 to 27 operates as follows:

Assuming the machine is mounted onta board, on a sheet of graph paper as for instance, 68 of Fig. 31 with the pointers H9, |20 and |2| adjacent each other in the center of the machine and all pointing to the mark 12 which represents in price the last quotation of the previous day or session for a particular stock. At the same time the adjustable tape 91 is set by actuating either one of the hand wheels so that pointer |24 will indicate the closing price as graphically indicated by the mark 12, the tape 91 being provided with a range of figures corresponding to any possible range of prices of the particular stock. Assuming now that the transactions on the Stock Exchange are observed from the well known ticker tape, a transaction for the particular stock appears thereon which is, for instance, at the same closing price, 12 on the graph 69, the machine is not actuated. If, however, the price is higher by one-half the high button Yor switch |58 is depressed four times so that the solenoid |33 will be energized four times to impart a complete rotation of the rod 84 to move the pointers |2| and |24 and with them the slide |03 and its pointer ||9 four positions equal to four-eighths. Each succeeding transaction of kthe respective stock is precisely recorded in the preserve a permanent record, a vertical line 10 is then drawn between the pointers ||9 and |20 on the graph paper 60 with a horizontal closing price line 12, the latter point being the position at which the three pointers ||9, |20, and |2| Aare set for the following day or session.

Figs. 24 to 26 illustrate a quarter turn movement of the rod 84 which operation has already been referred to. e

Figs. 28 to 30 illustrate an extremely simple manual indicating and recording device which consists of a metallic base plate |64 having a series of perforations |65 near the peripheral edge thereof which are suitably spaced and which serve to mount the plate on a board by means of thumb tacks, not shown. A sheet of graph paper |66 is secured on the base plate by means of the thumb tacks. The indicating and recording devices |61, |68 and |69 each of an elongated pyramid Shape as shown in general in Fig. 30, is made of a magnetizable metal so that it will adhere on the paper sheet |66 even though the plate |64 is vertical. Each indicator is provided with apointed end |10 and a handle |1|. The device is used in a manner similar to the instruments described in the previous modifications in that the pointer |68 will indicate the high price, the pointer |61, the low price at any time during a days session of the stock market. As for instance shown in Fig'. 28, the pointers |68 and |61 may indicate the days high and low prices respectively and the pointer |69 the closing or last price. Lines are then drawn on the graph paper |66 similar to those shown in Fig. 3l.

y It is of course obvious that the quarter turn of the rod 84 may represent any desired unit or change in price or value. It is also obvious that not all the various details must be conjointly since the various elements may be used in any combination or sub-combinations Within the scope of the appended claims. It is also obvious that one machine may be used to precisely record and indicate the prices or fluctuations of more than one particular stock to thus obtain a composite of the stocks in question. If thus for instance two stocks are to be recorded the price change of 1/2 a point will require only a 1/2 turn of the rod 84 instead of a complete revolution as in the case with one stock, to thus obtain the average between the two stocks. It might also be explained' that the lights |56 and |51 may be used to instantly set up a visual signal to impart the information that a certain predetermined price has been reached which latter might not be immediately ascertained unless a careful observation is maintained on the pointers when a price or sale of the stock comes over the ticker and is set up into the machine. It is of course necessary to set the strips |01 and |08 previous to the opening session of the market and this setting corresponds to the values at which it isdesired to make a trade or transaction. The machines may obviously be used in various other ways as may be desired.
